HP-7302 Selective Conformal Coating Machine
Dual-Valve Simultaneous Spraying with ±0.02mm Repeatability
Advanced PCB Coating Productivity
The HP-7302 Selective Coating Machine offers unprecedented process
flexibility with its manually adjustable dual-valve design. The two
precision atomizing valves (H-905) can be positioned anywhere from
50mm to 260mm apart, allowing operators to optimize valve spacing
for specific board layouts—whether coating two separate narrow
boards simultaneously, covering wide areas in a single pass, or
positioning valves precisely around complex component geometries.
Precision Coating Performance
Each valve independently delivers the proven H-905 performance: 1mm
edge accuracy, low-pressure atomization, and compatibility with all
conformal coating types (50-1500 CPS). The servo-driven motion
system maintains ±0.02mm repeatability across the entire 450*450mm
work area, while the electrically adjustable conveyor (50-450mm)
accommodates diverse PCB sizes. For contract manufacturers and
high-mix facilities running varied board types, the HP-7302's
adjustable dual-valve configuration delivers unmatched versatility.
Key Features & Benefits
- Dual H-905 precision atomizing valve configuration delivers
exceptional spray quality with fine atomization and precise pattern
control
- Manually adjustable valve spacing from 50mm to 260mm provides
flexibility to coat two separate areas simultaneously or two boards
side-by-side
- Dramatically increases production throughput without increasing
floor space requirements
- Servo motor + ball screw module drive system across X, Y, and Z
axes ensures outstanding performance
- ±0.02mm repeatability for precise selective coating around
sensitive components and connectors
- High-speed operation with maximum X/Y speeds of 800mm/s and Z-axis
speeds of 300mm/s
